Prusament PLA Lightweight Natural: lightweight filament for demanding projects

Prusament PLA Lightweight Natural 1kg (NFC) uses active foaming: additives expand when heated in the nozzle and create a lightweight foam structure. The result can be prints up to 65% lighter than standard PLA. With suitable settings, approximately 2–3 times more models can be printed from the same weight of filament. The actual result depends on the print settings and the degree of foaming. (blog.prusa3d.com)

Applications for lightweight PLA

• RC aircraft and drones: parts for projects where low weight is important.
• Cosplay and costumes: lightweight masks, props, and costume parts.
• Interior models: the matte texture reduces the visibility of layers.
• Floats and insulating inserts: the foam structure offers good thermal insulation properties and floats well on water. (prusa3d.com)

Recommended print settings

Foaming increases as the temperature rises, so the extrusion multiplier must be adjusted accordingly. Start with a profile for Prusament PLA Lightweight and perform calibration before printing the final model. Do not exceed 250 °C: material degradation and the release of potentially hazardous fumes may occur. (prusa3d.com)

OpenPrintTag NFC spool

The rewritable OpenPrintTag NFC tag stores important material data. You can read it using the Prusa mobile app; it also works offline. (prusa3d.com)

Filament care and print finishing

The material is hygroscopic, so store it in a dry place. Recommended drying is 5 hours at 55 °C. Expect increased stringing caused by foaming and subsequent model cleanup. The surface is prone to scratching and the material has low heat resistance. (blog.prusa3d.com)
